A low-cost, direct reading instrument used for both air velocity and static pressure tests. Excellent for service work on air conditioning, heating and ventilating equipment. Direct readout, both high and low range. Shows supply and return grille velocities, duct air velocities, furnace draft, pressure drop across filters. Designed on the variable area flowmeter principle, Model 460 gives consistent, accurate measurements. No tedious calibration. Rugged plastic for rough daily service. Complete pocket-size kit includes: air meter return and supply grille probes, angle connector, air velocity calculator, cleaning materials, instruction card and carrying case.
